Add Easter egg at the Dojo prompt.

[sigilante]

It's always irked me that our wordmark ~Urbit is not valid to type at the Dojo prompt.

Well, no longer is this a problem!

Maybe we should UIP this first, but it's a nice little Easter egg.

The code is a little rough in that it simply adds an alternate parsing route to ~Urbit that directly invokes the targeted thread. Since it's a special case, it probably has to/should be handled separately everywhere.

What does it look like constructed out of ~ characters instead?

Would be nice to see something like this printed at boot too.

I'd actually like to put in a nice little animation in text but that'll require a bit of Dill work.
